The Illumina BeadArray expression analysis revealed significant changes in the expression of genes in several functional categories at 1 and 4 hours following formoterol administration, including genes involved in skeletal muscle hypertrophy/growth, myoblast differentiation, metabolism, circadian rhythm, transcription, histones, oxidative stress, angiogenesis, solute carriers, apoptosis, cell cycle, cancer, DNA repair, and the ubiquitin-proteasome system. This evidence concerns the gene UBC and cancer.
